ASTM F3525/F3525M-21(Specification)
Standard Specification Fabricated Fittings of Crosslinkable Polyethylene (CX-PE)

SCOPE
1.1 This specification establishes requirements for fabricated fittings intended for use with outside-diameter controlled CX-PE pipe and tubing. These fittings are manufactured by heat-fusion joining shape-modified CX-PE components prepared from pipe, molded fittings, sheet, billet, or block. Included are requirements for materials, design, workmanship, minimum dimensions, marking, test methods, and quality control.  
1.2 Pressure rating of the fabricated-fitting design is beyond the scope of this standard and shall be established by the fitting manufacturer.  
1.3 Fittings manufactured in accordance with this specification are primarily intended to be joined to CX-PE pipes and used in CX-PE piping systems that are commissioned in accordance with a pipe manufacturer recommended commissioning practice. In addition, fittings manufactured in accordance with this specification that are ≥65 % crosslinked prior to installation can meet the additional requirements of Specification F2829.  
1.4 The pressure rating determined for a fitting will result in the fittings’ equivalent dimension ratio (EDR). The EDR specified by the fitting manufacturer is the DR of the piping system for which the fabricated fitting is intended to be joined. This standard specifies that fittings be fabricated from pipe sections of a lower DR than pipe that the fabricated fitting is intended to be joined to. This standard follows the pattern of Specification F2206 which specifies that the wall thickness of fabricated multiple segment elbow fittings shall be a minimum of 22 % more than the pipe to be joined to for example.
Note 1: Increased wall thickness alone is not necessarily sufficient to produce fittings adequate for use. Increased wall thickness without consideration of proper material placement can be detrimental to performance. Finite element analysis studies have shown that abrupt changes in fitting wall sections, such as between a heavy socket hub and body wall, concentrates stress at the transition point. Normal stresses from flex, pressure, expansion, and contraction in a plastic piping system can break a fitting at this point. Short transitions from 22 % thicker fittings to pipe or tubing create a similar condition.  
1.5 Design of fabricated fittings is outside of the scope of this standard. Requirements related to thicknesses and taper angles are intended to differentiate potentially good, fabricated fittings from fittings with a high risk of failure. Users of the standard are advised that for large or made-to-order fittings, minimal testing is required by this standard, and it may be insufficient itself to identify improperly designed and produced fittings made in accordance with this standard.

Standard Specification for Cold-Formed Welded and Seamless Carbon Steel Structural Tubing in Rounds and Shapes

ABSTRACT
This specification covers cold-formed welded and seamless carbon steel round, square, rectangular, or special shape structural tubing for welded, riveted, or bolted construction of bridges and buildings, and for general structural purposes. This tubing shall be produced in both welded and seamless sizes and must have the chemical requirements of carbon, manganese, phosphorus, sulfur, and copper. The steel shall be produced by either open-hearth, basic-oxygen, or electric-furnace melting process. When steels of different grades are sequentially strand cast, the steel producer shall identify the resultant transition material and remove it using an established procedure that positively separates the grades. The tubing shall then be made by a seamless or welding process. Welded tubing shall be made from flat-rolled steel by the electric-resistance-welding process. The longitudinal butt joint of welded tubing shall be welded across its thickness in such a manner that the structural design strength of the tubing section is assured. Tension test and flattening test shall be conducted to the specimens. All tubing shall be inspected at the place of manufacture to ensure conformance to the requirements of this specification and must have a workmanlike finish that is free from defects.
SCOPE
1.1 This specification covers cold-formed welded and seamless carbon steel round, square, rectangular, or special structural tubular shapes for welded, riveted, or bolted construction of bridges and buildings, and for general structural purposes.  
1.2 This tubing is produced in both welded and seamless sizes with a periphery of 88 in. [2235 mm] or less, and a specified wall thickness of 1.000 in. [25.4 mm] or less. Grade D requires heat treatment.
Note 1: Products manufactured to this specification may not be suitable for those applications such as dynamically loaded elements in welded structures, etc., where low-temperature notch-toughness properties, which are typically measured by Charpy Impact testing, may be important. There are other ASTM standards that do have CVN requirements and may be more suitable for those applications.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.  
1.4 The text of this specification contains notes and footnotes that provide explanatory material. Such notes and footnotes, excluding those in tables and figures, do not contain any mandatory requirements.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Specification for Seamless Carbon and Alloy Steel Mechanical Tubing

ABSTRACT
This specification covers for several grades of carbon and alloy steel mechanical tubing, either hot-finished or cold-finished. The steel used in the mechanical tubing may be cast in ingots or may be strand cast. When steel of different grades is sequentially strand cast, identification of the resultant transition material is required. The seamless tubing is a tubular product made without a welded seam. It is usually manufactured by hot working steel, and if necessary, by subsequently cold finishing the hot-worked tubular product to produce the desired shape, dimensions and properties. The tubes shall be furnished in the following shapes: round, square, rectangular and special sections. Heat analysis shall be made to determine the percentages of the elements specified. If secondary melting processes are used, the heat analysis shall be obtained from one remelted ingot or the product of one remelted ingot of each primary melt. The tubing shall be coated with a film of oil before shaping to retard rust when specified
SCOPE
1.1 This specification covers several grades of carbon and alloy steel seamless mechanical tubing. The grades are listed in Tables 1-3. When welding is used for joining the weldable mechanical tube grades, the welding procedure shall be suitable for the grade, the condition of the components, and the intended service.    
1.2 This specification covers both seamless hot-finished mechanical tubing and seamless cold-finished mechanical tubing in sizes up to and including 12 3/4 in. [325 mm] outside diameter for round tubes with wall thicknesses as required.  
1.3 The tubes shall be furnished in the following shapes, as specified by the purchaser: round, square, rectangular, and special sections.  
1.4 Supplementary requirements of an optional nature are provided and when desired shall be so stated in the order.  
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets or parentheses. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order. In this specification hard or rationalized conversions apply to diameter, lengths and tensile properties. Soft conversion applies to other SI measurements.  
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
